Kongsberg /Tore seem powersupply
« on: May 04, 2020, 04:44:34 PM »
Hello good people !

I accidentally shorted this powersupply board for a preamp module from the norwegian broadcast company built by Kongsberg/Tore seem .

I shorted the diode , the silver one in the picture, with the markings ZM47 .  I think its a germanium diode.

My problem is that i donĀ“t know what  kind of diode i can use to replace the germanium one , since the original it not obtainable.

Can anybody guide me in the right direction ?

Could it be a 47V zener diode for phantom voltage?
..note to self: don't let Harman run your company..

You might be right.  Its running on 48V because of the system at Norwegian broadcasting , the same reason that neumann begun with the 48v. So its probably the same

Thank you very much
